RBL Configuration

[Laskie, Norman]

Where in the MailScanner / Sendmail configuration could a particular RBL be configured?  We received a notification that we are heavily utilizing a particular list, but can find no evidence on our edge boxes of it being configured (besides in spam.lists.conf which based on the config file translates the names of the "Spam List" values to the real DNS names of the spam blacklists).

Thanks,
Norman
